Active Emergency Braking - Opel ASTRA K 2015 Owner's Manual

190 Driving and operating
If Adaptive cruise control is active,
this page shows the alert sensitivity
setting instead of following distance
setting 3 179.

Active emergency braking

Active emergency braking can help to
reduce the damage and injury from
crashes with vehicles and obstacles
directly ahead, when a collision can
no longer be avoided either by
manual braking or by steering. Before
the active emergency braking
applies, the driver is warned by the
forward collision alert 3 187.
The feature uses various inputs (e.g.
camera sensor, radar sensor, brake
pressure, vehicle speed) to calculate
the probability of a frontal collision.
9 Warning
This system is not intended to
replace the driver responsibility for
driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system may not react for
animals. After a sudden lane
change, the system needs a
certain time to detect the next
preceding vehicle.
The driver shall always be ready to
take action and apply the brakes
and steer to avoid collisions.
Functionality
If equipped only with front camera the
active emergency braking operates in
forward gear above walking speed up
to 80 km/h.
With radar sensor active emergency
braking operates in forward gear
above walking speed at all speeds.
Number plate mounting 3 222.
A precondition is that forward collision
alert is not deactivated in the vehicle
personalisation menu 3 124.
The system includes:
● brake preparation system
● emergency automatic braking
● forward looking brake assist
● intelligent brake assist (only with
radar sensor)
Brake preparation system
When approaching a vehicle ahead
so quickly that a collision is likely, the
brake preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or
automatic braking is requested.
The brake system is prepared so that
braking can occur more rapidly.
If equipped only with front camera the
system operates up to a speed of
80 km/h.
